In the world where magic and curse falter, can the power of "reasoning" really reach the truth?

Note:
Hey guys. I've got kind of an unusual suggestion here, a Non-LN Japanese mystery novel, by the author of Hyouka, Oreta Ryuukotsu! I'm a fan of the Koten-bu series (RIP my dreams of having an official English hardcover) and have found myself really wanting to read some of Yonezawa's other works. I can't even remember how I found this novel of his in particular, probably serendipity, I just remember running upon it some years ago and finding myself rather infatuated with the idea of it. I'd essentially resigned myself to never getting the chance to read it since the odds of some random mystery novel (not even an LN) being translated were nigh zero. However, while perhaps a suboptimal solution, as of 2015 Oreta Ryuukotsu has actually been receiving a manga adaptation, which makes the odds of me (and you) getting the chance to consume the story in some capacity look many times less grim. But, at any rate, I'm here to recommend the Oreta Ryuukotsu Novel (and the manga too, I guess) for translation and gauge interest. So, is anyone else here interested in seeing a translation of the Oreta Ryuukotsu Novel, Manga, or both?

In many fantasy series, the main character will meet trouble when registering as an Adventurer at a Guild. This trouble often comes in the form of another Adventurer picking a fight. This is the story of that Self-Proclaimed Newcomer Trainer.

Why:

It's a one-shot volume about that trope-asshole that typically picks a fight with the protagonist at a Guild in most fantasy series. So I think it'd be interesting to read it. J-Novel Club doesn't have many one-shot series that were intended as one-shots. So this would help bump up that number a bit.

Sypnosis: After defeating the Demon King and saving the world, Sion was exiled to the border. Here, the strongest Hero enjoyed his slow life with 4 capable onee-san maids.

Reasons to pickup: ONEE-SAN! MAIDS! BEST MATCH! For real though, the lack of older sister type heroines in published LNs is a shame. I want to be pampered by an older girl, too! Plus, the contrast between the young hero having OP Powers but also shouldering the consequences and responsibilities coming with being the strongest interesting way to tackle at this typical archetype. Having the heroines being the emotional support for him is also the prime recipe for the heart-warming romance to come.

Kousuke Kurono was an Avenger. After being raped, his beloved little sister was left out in the cold and froze to death.

From the time he was 13-years old, Kousuke made use of any possible means in order to exact his revenge. 5 years had passed, he achieved his revenge, but having lived solely for the sake of revenge, at the moment his revenge came to fruition, afterwards he couldn’t muster up the willpower to live on. That’s why, with the same knife he used to kill the culprits, he slit his own throat. However, he then heard a voice; “Is that not wasteful?”. When he came to, he found not his home, his country, nor his world——It was another world.

Impression
Recently got manga adaptation, 4 chapters in so far. Story starts kinda dark, but has potential to become interesting. Definitely worth keeping an eye on it for the future, or even better, getting the light novel licensed and translated ;)
